Revision3, a popular Internet-based TV network started in part by Kevin Rose, just quietly released not 1, not 2, but 6 apps for 6 of their popular shows.

The apps allow you to stream episodes in standard or hi-def, view comments, and view individual show segments - the Segments tab acts a video table of contents of sorts - a subtle feature, but it really makes all the difference.

There aren't many features besides the ones I've listed, but what the apps do do (ha), they do very well.
